When I select the device, the message "This chip needs a wire jumper from Address header A23 to ZIF Pin24" is displayed. The GQ-4X doesn't have an address header so I tried programming them with no jumper wire connected. Both fail at exactly the same address at 51% complete. What can I do to get these working? Where is the equivalent of A23 on this programmer? [/quote]    Insert an Image File Check here to include your profile signature.
